Это моя форма, когда пользователь нажимает на ARE YOU A QUESTION IE IE или NO. В НЕТ вся строка таблицы, которая имеет идентификатор cit, становится скрытой, но когда пользователь нажимает кнопку "Да", она снова отображает всю строку таблицы но моя проблема заключается в том, когда пользователь нажимает "НЕТ" и после этого нажимает "ДА", отображается строка таблицы, но она показывает мне меньше ширины
